I have downloaded the Zip and extracted all the files but I have another app other than SDR# that I want to use. I can’t get the computer to recognize the folder I extracted the files to as a driver. would these files be relevant to any other SDR so were like GQRX or GURC? How do I make use of the dongle without SDR#?

So the version of zadig.exe that install-rtlsdr.bat is incorrect. If you get a message say that Zadig is Corrupt or unreadable is is because, it’s not really an .exe but a file that probably contains an HTML 404 message or something. You’ll need to go to the Zadig website and install the program (which as of July 2019 is called zadig-2.4.exe manually into the sdrsharp-x86 folder. You can delete that other zadig.exe which isn’t the Zadig we need.

Hi, I run zadig-2.4.exe and have replaced the driver for Bulk-In, Interface 0 with WinUSB v6.1.7600.16385 on Windows 10 1809 x64 but in SDR# v1.0.0.1703 when I select RTL-SDR(USB) I can’t see the device in “configure source” and when I press the play button I get the error “no device selected”. I have tried the x32 and the x64 Version of rtlsdr.dll from 2014 but also the x32 and x64 Version of librtlsdr.dll from the 14. of July 2019. When I use rtl_test.exe I don’t get any error.

I’ve tried every trick I can find here. I can’t get the bat file to load peoperly. Zadig has 0 bytes in it and won’t run because of this. I tried to download the stuff manually and still no joy. I can see why people are getting frustrated. I’m beginning to wonder if its worth it myself.

I just checked the bat file and it’s still functioning correctly. If you’re having trouble with it it’s likely that your on a misconfigured or locked down system, or your Antivirus is blocking it. Either way a manual install should work if you can’t get the bat file to download the files. When you run a manually downloaded zadig, what happens?

I just try to install and use the DVB-T+FM+DAB dv3 (820T2 & SDR)
I use Win 7.
It seems I can install the driver by Zadig… the insatalled driver WinUSB v6.1.7600.16385 usbid: 0BDA 2838 00
But the SDRSharp (SDR#) can’t see the device. At the configure source’s Device is grey (empty)
When i hit the run button I got : No device selected.
I set the RTL-SDR (USB) before for source.

My rtl Sdr 2838 works fine on my Android tablet. Tried downloading all drives and software so I can operate it on my Acer aspire x desktop with 2.34ghz processor and Windows 8 . I had no luck . What am I doing wrong . Have sdr Sharp . Keeps saying no device found . And looked in devices and rtl sdr driver isn’t installed . Help please

I just bought an android stereo for my car. My goal is to use the SDR as scanner and Shortwave receiver as an added feature in the radio. The radio runs android 5.1 and is not rooted. The driver installs good, but doesn’t work. As soon as I open any app and tries to deal with the driver, the program just disconnect. However I tested another app that doesnt use the driver (the one that tracks planes) and works pretty good. How can I make the SDR driver work om android 5.1?

OK I just bought 2 V3 USB RTL-SDR radios. One works.
In Zadig the one that works shows up as RTL2838UHIDIR Wheras the one that doesnt shows up as
RTL2832U. I used the same procedure on both to change the drivers. The one that doesnt work gets a response of ‘Cannot access RTL device in SDR Sharp. How can I fix it.?

Did that. SDR# runs and works although if I select a new Frequency Manager selection, etc. the waterfall doesn’t change and the audio doesn’t change – unless – I turn the software off and on again – and then it works on the new freq in tandem. Also – when it loads the RTL-SDR USB driver the software only shows a Generic radio and that works as above. This is on a new PC. On my old PC it shows the actual RTL-SDR instead of a Generic radio.

Installation is tricky but possible. Read the directions from the Quick Start Guide and follow them closely. Install your SDR# directory in C:\ not Program Files. When logged in as root, set that SDR# directory to have write permissions also (default read only). Then go into Norton or other antivirus and set an exception for your SDR# directory and all subfolders. It is key to make sure that the .bat installs properly. It seems the WinXP version zadig works in Win7 also.

Not sure about Win10. It’s too new to support many programs and drivers so my sympathies. I’ll try it in a year or 2 when they work out the bugs and driver incompatibilities.

What is RTL-SDR

The RTL-SDR is an ultra cheap software defined radio based on DVB-T TV tuners with RTL2832U chips. The RTL-SDR can be used as a wide band radio scanner. It may interest ham radio enthusiasts, hardware hackers, tinkerers and anyone interested in RF.
